The HP J4858C is a ProCurve Gigabit-SX-LC Mini-GBIC, a 1000Base-SX transceiver with an LC duplex connector for multimode fibre runs up to around 550 metres, fitting the mini-GBIC slots on ProCurve GL, XL and zl-series switches and modules. It is a short-reach optical transceiver intended for building or campus-level fibre links rather than long-haul spans, commonly used for switch-to-switch uplinks or connecting fibre-attached servers within a single site. This is the correct spare for restoring a failed Gigabit fibre uplink or for adding a fibre port to an existing multimode-fibre installation. Specifiers should confirm their fibre type (multimode, not single-mode) and link distance before ordering, since an SX transceiver will not close a single-mode long-haul span. Tech-Star (UK-based, shipped worldwide) supplies refurbished HP hardware for engineers maintaining or expanding existing ProCurve fibre installations.
